Ribs 2O and 21 are formed as a consequence of the formation of said recesses 17 and 18, these ribs being respectively in the casing sections 3 and ll. Portions 16 and 19 of the bolt 11, when this bolt is thrown to a locking position, engage the outer faces of said ribs to hold the sections of the casing together. l/Vhile the casing is preferably formed as described, l do not wish to be limited to such a construction, in carrying out the balance of my invention.

The bolt proper or main bolt 22 is arranged to slide back and forth within aholding sleeve 23 that is suitably assembled with the casing section el to which the sleeve is secured, by means of screws 24 passing through the strap 25 and into the casing section l. The bore of the sleeve is in register with an opening 26formed in the rotatable steering post 2. rl`he screws 24 serve to clamp the stationary steering column 1 between the casing section 4; and thestrap 25, the screws 9 supplementing the screws 211 in this function.

A bolt throwing coiled spring `27 is held at its outer end in a recess in the key actuated bolt 11 and at its inner end engages thev head 28 upon the outer end of the main bolt 22. Then this 'spring is adjusted to and is `free to perform its function it presses the main bolt 22 inwardly to cause it to enter the opening 26 in the steering post 2 when the steering post is suitably positioned, as indicated in Fig. rThe spring 27, in order that it may perform its function, is bodily inwardly adjusted by the key actuated member 14 when this member is turned tov locking position by the key 15. lf this spring, having been bodily moved toward the steering post 2 by the inward movement of the bolt 11, is free to perform its function by other mechanism that is hereinafter to be set forth, it will throw the bolt 22 into locking position and into indirect engagement with the inturned end of the bolt withdrawing or positioning member 29 that is mounted upon the bolt 11 that is directly actuated by the element 13 upon the keyaetuated member A, this member 20 thus being a key actuated member. FV hen the main bolt 22 is to be drawn from its. locking position the other bolt 11 is turned by the key 15 whereupon the withdrawing or positioning member 29moves the bolt 22 outwardly, the spring 27 then bodily moving with said withdrawing member 29 and the bolt 11, the spring not then functioning. A restraining member 3() is interposed between the inturned end of the key actuated withdrawing member 29 and the bolt head 28, this restraining member holding the bolt 22 in the outward position in which it is placed by the witl'idrawing member 29 when the restraining member itself is held as will be described. The restraining member is held in its functioning position by a detent 31. A coiled spring serves to place the detent 31 in position to hold the restraining member 30 when the bolt has been withdrawn to its outer or unlocking position, the restraining member 30 being also withdrawn to its outward position at the same time by the key actuated member 29. The spring effected movement of the detent 31 is desirably limited by the projection 50 formed upon` the restraining member 30. llllien the restraining member 30 is held by the detent 31 in functioning position, the locking member 14 may` be turned to locking position, as illustrated in Fig. 3, without permitting the spring 27 to function, the spring being then placed under increased compression owing to the fact that the bolt 11 is forced toward the held bolt 22. The key 15 may then be wit-hdrawn from the lock and need not again be inserted in order that the main bolt 22 may be placed in locking position as l have provided means whereby the detent 31 may be withdrawn from engagement with the restraining member 30 to permit the spring 27 to distend from its compressedV adjustnient shown in Fig. 3 to its distended form shown in Fig. 5, the spring 27, when thus released, alone serving to place the bolt 22 in locking position without the aid of the key. .In order that .the detent 31 may be released so that the spring 27 may place the bolt 22 in locking position,'lf mount said detent upon a rod 33 that is slidably mountedy in the casing section '-1, this rod having a knurled head 84C upon the exterior of said casing section whereby the rod may be pulled outwardly to move the detent 31 outwardl from the )osition shown in Fior.

Features of novelty not herein claimed form the subject matter of a division of this application Serial No. 608,?87, tiled Dec., as,

lNhile' 1 have herein shown and particularly described the preferred embodiment of my invention l do not wish to be limited to the precise details of construction shown asy changes may readily be made without departing from the spirit of my invention, but having thus described my invention 1 claim as new and desire to secure by Letters Patent the following 1. The combination with a two part casing having ribs on the two parts thereof and within the casing.; of a lock inclusive of a bolt in engagement with the outer faces of said ribs in one adjustment of the bolt rfi and free of engagement with the outer faces of said ribs in another adjustment of the holt.

2. The combination with a two part casing having ribs on the two parts thereof and within the casing; of a lock inclusive of a bolt in engagement with the outer faces of said ribs in one adjustment of the holt and free of engagement with the outer face of one of said ribs in another adjustment of the bolt.

3. The combination with a two part casing; of a screw threaded into one of the casing parts and engaging both casing parts for directly holding the two parts of the casing together and formed with an annular groove; and a lock that is inclusive of a bolt adjustable into and out of said annular groove to prevent or permit effective turning of the screw.

In witness whereof, I hereunto subscribe my name this 23rd day of May, A. D. 1921.
